In an experiment, mice were fed glucose (C6H12O6) containing a small
amount of radioactive oxygen. The mice were closely monitored, and after a few
minutes radioactive oxygen atoms showed up in _____. (eText Concept 9.3)

In the citric acid cycle, for each pyruvate that enters the cycle, one
ATP, three NADH, and one FADH2 are produced. For each glucose molecule that
enters glycolysis, how many ATP, NADH, and FADH2 are produced in the citric
acid cycle? (eText Concept 9.3)

When a poison such as cyanide blocks the electron transport chain,
glycolysis and the citric acid cycle also eventually stop working. Which of the
following is the best explanation for this? (eText Concept 9.4)

a.
They run out of ADP.

b.
Electrons are no longer available from the
electron transport chain to power glycolysis and the citric acid cycle.

c.
A high level of NADH is present in the cell.

d.
The uptake of oxygen stops because electron
transport was inhibited.

e.
NAD+ and FAD are not available for glycolysis
and the citric acid cycle to continue.

e.
NAD+ and FAD are not available for glycolysis
and the citric acid cycle to continue.
